What are some easy, non-prescription methods of increasing my chances of conception?

Simple things include cutting down alcohol consumption (less than 2 units/day), stopping smoking, trying to get to your ideal bodyweight (both being over- and under-weight can reduce your ability to ovulate). ''Reducing stress'' is often quoted but in practice is not always easy to do! Ringfence time for eachother-evenings and weekends as many people nowadays get home too late for anything other than a shower and a quick bite to eat. Also, use an ovulation kit (easily bought at a pharmacist) to time your ovulation, hence the best time for intercourse.
